Hi Jason,

What do you mean by PD? USB type-C PD? BQ25890 is capable of doing all three above, except it will struggle to charge at 3A from a 5V due to input current limit of 3A. BQ25792 is the newest device, with the same D+/D- detection and slightly higher efficiency.

Regards,

Jeff

Jeff,

Do we have charger solution to support CC pin detection in Type-C as all-in-one solution?
